Reforming Forensics: Discover Magazine Features CSAFE Research in Recent Issue

Analyzing Bullet Markings

Discover magazine recently published an article discussing how academic researchers are investigating the foundations and legitimacy of forensic science. Reforming Forensics: Why Academics Are Challenging the Science Behind U.S. Criminal Justice describes how CSAFE research could help forensic science professionals carry out their work, and address the concerns raised in the 2009 National Research Council (NRC) and 2016 President’s Council of Advisors on Science and Technology (PCAST) reports.

Several CSAFE researchers were interviewed in the article:

  • Alicia Carriquiry, CSAFE director and Distinguished Professor and President’s Chair in statistics at Iowa State University
  • Brandon Garrett, CSAFE co-director and the L. Neil Williams, Jr. Professor of Law and director of the Wilson Center for Science and Justice at Duke University
  • Heike Hofmann, professor of statistics and Kingland Faculty Fellow, at Iowa State
  • Simon Cole, professor of criminology, law and society at the University of California, Irvine
  • Amy Crawford, a former postdoctoral research associate at Iowa State

From the article:

Statistics research doesn’t usually require weapons. But to develop their latest algorithm, Iowa State University statisticians Alicia Carriquiry and Heike Hofmann needed thousands of bullets fired from a small collection of handguns. So they put the firepower in their own hands, and hit the range.

For nearly a year, Carriquiry and Hofmann, supervised by sheriff’s deputies, unloaded round after round into a tube with Kevlar fibers. After each shot, they fished out the bullet and tucked it in a plastic baggie labeled with critical data: gun, barrel, shot number.

“If you had asked me a few years ago whether I was going to be doing this type of data collection, I would have said, ‘You’re crazy,’ ” says Carriquiry.

It’s not just bullets, either. Over the past several years, the professors and their collaborators have amassed 160 pairs of well-trod sneakers, over 2,000 handwriting samples and 129 poster boards spattered with pig blood. Scanned and digitized, the items became first-of-their-kind data for research on crime scene evidence.
